HERBERT A. CUTTING, OF DETROIT, MICHIGAN.

OIL COOLER AND CLEANER FOR INTERNAL-COMBUSTION ENGINES.

Application filed October 8, 1926. Serial No. 140.277.

Another object of my invention is to ap ply such a device to an internal combustion engine ofthe Ford type in such a manner that after the oil is cooled it is passed into the top of the transmission over the transmission bands of the Ford planetary gear system. The purpose of passing the cool oil over the bands is to prevent the glazing of the transmission bands with consequent chatter in operation, such as is well known with conventional installations.

Another object of my invention is to provide an improved filter in the auxiliary oil reservoir which may be easily installed and taken off. and which will remove metallic substances from the oil as well as other deleterious substances.

With the above and other objects in view, my invention consists in the arrangement,

combination and construction of the various parts of my improved device. as described in the specification. claimed in my claims and shown in the accompanying drawing, in which:

-Fi z. 1 is a side elevation of an internal combustion engine of the Ford type. shown more or less diagrammatically. with parts broken away to illustrate the transmission bands.

Fizz. 2 is a side elevation of the auxiliary oil reservoir utilized in my invention. with parts broken away to illustrate the filtering insert.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

I have shown an internal combustion engine indicated generally as 5 having detachably secured thereto a crankcase 6. The en gine which I have shown is of the conventional Ford tvpe, although certain portions of my invention 'are equally a plicable to other types of engines. In the Ford type of engine. a depression 7 is formed in the crankcase 6 above which are positioned the bands 8 of the Ford planetary transmission. Oil is collected in the depressed portion 7 to a level above the bottom of the bands 8. In the conventional installations, when the oil becomes heated it glazes upon the working surfaces of the transmission bands, and causes a chatter when the bands are apare idle.

plied. For the purpose of doing away with this condition I provide an auxiliary oil reservoir 9 and a' pump 10 connected thereto by a pipe 11 so that when the pump is operated oil will be drawn through the pipe 12 from the crankcase (i and passed into the reservoir 9. The oil passes from the reservoir 9 through a. pipe 1?, to a point 14 in the ent me casing directly above the transmission hands 8. and passes from the pipe 13 over the top of the bands 8.

It will be apparent that the oil taken from the crankcase 6 to the container 9 will be cooled in the container because there are no working parts therein to heat it. and the incoming! air caused by the forward movement of the vehicle will atlect the same. It shoul also he noted that the reservoir 9 is located on the same lcvel a the crankcase 6 so that a constant level will be maintained be ween the reservoir 9 and the crankcase 6 with the result that a supply of lubricant w ll always be maintained in the reservoir 9. Thi i of particular advantage over the tvne of auxiliarv oil reservoir which is mounted above the crank case. which mu t result in the oil from the aun'iliarv re ervoir drainino' into. the crankc se when the cn iue and pump Thu a tcr a sutiicient amount of lubricant is provided to com en ate for that lubricant wh ch is in the auriliarv oil re ervoir whcn the pump i o erated. an oversunplv of lubricant will he maintained in the crankcase when the pump is not operating. I

In ord r to ha ten the coolin of the oil, the reservoir 9 is cormttated. or of star shan'c in cro s section. so as to increase the rad ation surface thereof.

For the purpo e of tiltcrinq the o l which is brou ht from the crankcas to the auxiliarv oil reservoir. I provide a screwthrcadcd tittin 14 on the end of the pipe11. which is adapted to be inserted in the screwthrc ded aperture 15 in the reservoir. Ex

tending into the reservoir from the can or fittinq 14 is a. permanent mannct-16 having a central aperture 17 which aligns with the passage of the pipe 11 so thatoil from the pipe 11 will pass through the aperture 17. A screen 18 enclos s the macrnet 16 and is also mounted on the cap'or' fitting 14 within the reservoir so that oil passing throuwh the magnet 16 will in turn pass through the screen 18. Mountedwithin the screen 18 directly above the upper end. of the magnet 16 is a battle 19 which is adaptedto direct downwardly such oil as passes through the aperture 17, spreading the oil soas to cause it to flow in a film over the outer surface of the magnet 16. Any metallic particles which may be maintained in the oil will be held by the magnet 16 so that they will not again -pass to the operating parts of the engine.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the spirit of my invention, and it is my intention to cover by my' claims such' chan es as may be reasonably included within the scope thereof.

What I claim is 1. An internal combustion engine having a crankcase adapted to receiveoil, a transmission housing and transmission bands in the housing, an auxiliary oil reservoir, means for delivering oil from the crankcase to the reservoir, and from the reservoir.

to and over the tops of said bands.

2. An internal combustion engine having openings connected with the crankcase a filtering unit inserted in the inlet opening comprising a plu a screen on the plug, a magnet within t e screen and means for dehveringoil over the magnet and through the screen.

, 4. An internal combustion engine having 40 a crankcase adapted to receive oil, an auxiliary oil reservoir having inlet and outlet openings connected with the crankcase, a filtering unit inserted in'the inlet opening comprising a plug, a screen on the plug, a magnet within the screen, an oil passage through the magnet adapted to permit the entry of oil from the crankcase connection and a battle over the said oil assage to direct said oil over the sides of t e magnet.
